The disk array device includes a master controller and a slave controller. Upon adding identifying information indicating that write data has been stored in a buffer memory to the write request, the slave controller transmits, to the master controller, the write request to which the identifying information has been added as well as the write data. After having stored the write data, the master controller transmits the write request to which the identifying information has been added to the slave controller. Upon receiving the write request, the slave controller alters the attributes of the buffer memory where the write data has been stored, from the buffer memory to the cache memory."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Disk array device, disk array system and cache control method","description":"The invention proposes a disk array device that can improve response performance while maintaining data consistency even in the case a write request is received from a host device by a controller that","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8510506","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
